Risks of Living Donation
Usually, the operation involves no serious risk for the healthy donor. The procedure carries the same risk as anyone undergoing general anesthesia. Major complications due to kidney donation are rare, 1 in 1,000 cases.
Long-term problems are minimal but some have suggested there may be a small increase risk of developing high blood pressure or excretion of protein in their urine. None of these, however, have been conclusively shown to affect the long-term health of donors.
Donors are restricted from contact sports that pose a risk of trauma to the remaining kidney. Some occupations, such as the police, fire and military, have been known to deny employment to people with one kidney.
